I’m trying to drape an image over a terrain mesh in Rhino. I’ve imported the image into the textures panel. I then select the terrain and click apply planar mapping, drag the box from one corner of the top view of the map to the opposite. ‘UV/UVW (UV UVW):’ appears in the command box and I click enter. I then drag the texture image over the terrain. And then… the terrain turns black… which is not the ideal turnout.
